Description

Technical Field

[0001] The utility model relates to the field of computer cooling fans, in particular to a cooling fan with good waterproof effect. Background Art

[0002] The function of a computer cooling fan is to help dissipate heat by rotating the fan. When the computer is running, the internal components will generate heat. Without an effective cooling system, this heat may cause hardware damage or performance degradation. The cooling fan dissipates heat and ensures stable operation of the hardware by blowing air into the computer.

[0003] In the existing technology, although a certain computer cooling effect can be achieved during use, there is a defect that the existing computer cooling fan lacks efficient waterproofing, which causes the fan to accidentally enter with water during use, causing a circuit short circuit and causing serious accidents. In view of this, we propose a cooling fan with good waterproof effect to solve the above problem. Utility Model Content
